Why are Brass Threaded Fittings Stronger and more Durable than Other Materials?

As a key connecting component of the fluid delivery system, the material properties of brass threaded fittings determine the durability of the product. As a copper-zinc alloy system, the optimized arrangement of the internal grain structure of brass constitutes a strength support framework, and the solid solution strengthening effect of zinc element improves the mechanical bearing capacity of the alloy matrix. The micro-yield strength and plastic deformation threshold of the material used to make brass threaded fittings form a benign balance, and it is not easy to generate fatigue crack sources under cyclic loads. The self-repairing function of the oxide layer on the metal surface effectively delays the chemical corrosion process and avoids structural weakening caused by pitting.

In the thread processing of brass threaded fittings, the cutting performance advantage of brass ensures the geometric accuracy of the meshing surface, and the continuity of metal streamlines at the microscopic level maintains the uniformity of contact stress distribution. Compared with other metal materials, the thermal conductivity characteristics of brass help to quickly dissipate local friction heat and inhibit the thread biting phenomenon caused by high temperature. The stress relaxation characteristics of the material itself allow the sealing surface pressure to remain stable under the action of preload, which is the fundamental guarantee for its long-term anti-leakage performance.

In a dynamic vibration environment, the damping coefficient characteristics of brass can absorb the mechanical energy transmitted by the system and reduce the resonance risk of the brass threaded fittings connection structure. The balanced design of dislocation movement resistance and slip coefficient at the grain boundary enables the pipe fittings to withstand sudden impact loads without causing brittle fracture due to excessive hardening.
